My first exposure to Adult Swim was back in 2002, and the show I think was Big O that was the first thing I watched with Adult Swim. My memory is quite hazy seeing how it was over a decade ago. I do remember that Pilot Candidate and Yu Yu Hakusho were among the shows airing back then. Anyway, as far as Toonami goes back when it was on CN, DBZ was the first thing I watched.

I caught first caught Toonami/Midnight Run back around 1999, though my memory is very fuzzy until about 2001. Digimon Adventure 01, DBZ, Pokemon, classic YuGiOh, and Sailor Moon are my first "loves." They strongly inspired the artwork of my youth. Most notably, YuGiOh pushed me into a dragon craze during 4th and 5th grade. I had a red, plastic folder that I filled with pages of various types of dragons that I made up. I seldom had access to Cartoon Network when I was a kid, but I made do. Me attaching myself to Inuyasha around 2004 (I was 11-12) marks the start of my growing interest in more mature themes. Before Inuyasha, shows like Outlaw Star, YuYu Hakusho, and Big O flew miles over my head.

Oh wow! Nostalgia coming back to me. DBZ, Outlaw Star, YuYu Hakusho, Sailor Moon, Tenchi Muyo, and I think it had the first gundam series. I am trying to remember if Cardcaptors was in the same channel or not. Damn my memory
